print method

Future<String?> print(List<ItemPrintModel> items)

Sends a list of print instructions to the POS device for processing.

This method takes a list of ItemPrintModel objects, which describe the individual instructions (text, QR code, barcode, etc.) for printing.

The actual printing process is delegated to the platform-specific implementation of the GetnetPosPlatform.

If an error occurs during printing, the error is rethrown.

Example:

final items = [
  ItemPrintModel.text(
    content: "TEXTO CENTRALIZADO",
    align: Align.center,
    fontFormat: FontFormat.medium,
  ),
  ItemPrintModel.qrcode(
    content: "https://example.com",
    align: Align.center,
  ),
];

final result = await getnetPos.print(items);
print(result); // "Printed successfully"

items - A list of ItemPrintModel objects describing the print instructions.

Returns:

• A Future<String?> that resolves to a success message, or null if the operation fails.

Throws:

• Any error encountered during the printing process.

Implementation

Future<String?> print(List<ItemPrintModel> items) async {
  try {
    // Delegate the printing process to the platform
    return GetnetPosPlatform.instance.print(items);
  } catch (e) {
    // Emit the error through the stream
    rethrow;
  }
}
